Shoot stuck in deletion due to stuck `ManagedResource`

Yeah, using PATCH makes sense.

Still, I'm not sure, why grm didn't retry the reconciliation...

Same here, I still need to try to reproduce it. As said yesterday, it might also be the case that it "just" was in an exponential backoff and would have retried if I would have waited longer.

Hmm, not sure if this solves the issue, but we should switch to patching finalizers and using the c-r helper funcs like here:
https://github.com/gardener/gardener/blob/9af2e8a04a08cb78c66bbdc0ab47af577c5b28d2/pkg/controllerutils/finalizers.go#L35-L55

Still, I'm not sure, why grm didn't retry the reconciliation...

I also had a short look and currently I don't see any obvious reason. For @timebertt 's suggestion in #78 (comment) -> #87.

[rfranzke]

OK, thanks @ialidzhikov, then let's
/close
this issue for now as there are no clear steps for reproduction anyways and as I wasn't sure whether it's just exponential backoff.
#87 is merged and will definitely help.
In case we see this problem again we can reopen the issue, of course.
